There was no indication that the Automatic Braking System, Air Bags and Seatbelts were not working properly. In August 12, 2021, I was in an auto accident where I rear-ended another dodge car. The air bags did not deploy and Onstar was not notified. I believe I hit the steering wheel. I went to the emergency room and have seem my primary doctor once. I have a follow-up appointment this week for pain in the middle of my breast bone.
